业务背景：
有时候我们可能对自建屏幕上的字段要进行双击操作，要触发自建屏幕的双击需要设置一些东西，本文将介绍一种触发自建屏幕字段双击的例子。
解决步骤
- 新建一个程序，然后再新建一个屏幕，注意勾选回应双击
- 处理屏幕的PBO和PAI，设置STATUS和USER_COMMOND.
-

其中模块STATUS_0100和USER_COMMAND_0100是需要我们完成的，其他字段皆是TAB_CTRL向导模式生成的。
- 设置STATUS，注意设置F2（鼠标双击，这是一个SAP预设的功能）的功能码（其实我们注意观察的话，可以看到标准的SAP STATUS都是设置了F2的功能码的）
- 编写逻辑代码
